... 28. A: (91 4) (98 0) B: (95 0) (94 4) The best answer is B. The best way to solve this question is by using the formula: (X - Y)(X + Y) = X 2 – Y 2 . Column A = (94 7 – 33) (94 7 + 33) = 94 7 2 ... therefore the answer is not distinct. Column B = (94 7 + 3) (94 7 – 3) = 94 7 2 – 3 2 . Now the answer is obvious, column B is greater. 29. A: 16 S B:   25.0 16 T AI: T...
